No ZFS pools located, can't boot

[BSDLover101]

hi all

I have 9-CURRENT with tons of stuff on ZFS (entire drive).
I was out of this computer for a while and today I couldn't boot and saw just this:

"gptzfsboot: error   1  lba 1"
"gptzfsboot: error   1  lba 64"
"No ZFS pools located, can't boot"

now I'm running UFS MY GUID LABLE

[zip@piger /home/zip]$ gpart show

Looks like something important has evaporated...
I read about v28 update and same problem but I don't remember I did such update.
Anyway I tried what's recommended there but without success.

What actually could happen? How to revive the installation?

Would appreciate if any method exists for fixing this problem.

Does the actual pool still exist ? Boot into the fixit option of the DVD and see what might be the cause of this.

If you are not booting from the zpool, why are you using gptzfsboot? Shouldn't you have gptboot?
